The first two films work because they mirror each other.

A small pod carrying a droid is launched from the hanger of an Imperial Stardestroyer and lands on an extreme wilderness world.

After successfully completing it's mission an attack is launched to take down a power reactor.

The droid is hit by enemy fire.

Waves of defender craft are launched and pick off the attack craft one by one until the remaining attacker hits the target.

Only everything is in reverse, the Imperial ship is pointing ahead, instead of a hot desert we have a frozen ice world, instead of the Rebels attacking the Death Star it's the Imperials attacking the Rebels.

Instead of happening at the end of the film it happens at the beginning.

It can't be accidental it's clearly and deliberately staged that way.

So this sort of patterning in the whole sequence of films may well be deliberate. The difference is the first two films are almost perfect films with strong acting, tight editing and astonishing production values.

The other four films are not.
